What are the forces acting on the chandelier?

Click For Summary

Homework Help Overview

The discussion revolves around identifying the forces acting on a chandelier, specifically focusing on tension and normal forces in relation to its equilibrium. Participants are exploring the dynamics of forces in a suspended object scenario.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants are attempting to clarify the forces acting on the chandelier, particularly questioning the presence of normal forces and their relationship to tension. There are inquiries about the concept of equilibrium and how Newton's laws apply to the situation.

Discussion Status

The discussion is ongoing, with participants seeking clarification on the concepts of equilibrium and forces. Some guidance has been offered regarding the nature of normal forces and the application of Newton's laws, but there remains a lack of consensus on the understanding of these concepts.

Contextual Notes

Participants are working with the assumption that the chandelier is in equilibrium, and there are references to the need for a comprehensive list of forces, their directions, and points of application. The discussion includes a focus on the implications of these forces in a real-world context.

Homework Equations





The Attempt at a Solution



I want to know what are all the forces acting on this object.
If the object is 10N , the tension force suppose to be 10N. But wouldn' there be a normal force acting between the point touching the ceiling and the ceiling since ceiling is a surface?

Consider the equilibrium of the chandelier.
Now consider the equilibrium of the chandelier + Rope System.
Apply Newtons laws.
You will arrive at the answer.
 
what do u mean by equilibrium of the chandelier??
You mean Newton's 3rd law, every reaction force have an action force, i guess u are saying there is a normal force but there is also a reaction force acting back?
sorry, i don't quite get it, can u be more clear?
Thanks

There is force at the junction of suspender and ceiling. The force is normal to the ceiling. In relation to the suspender, the force is normal to the cross section of the suspender. Does that help?
Try standing up. There is a compression force between your feet and the ground. The force is normal to the plane of the floor and it is normal to the horizontal cross section of your body.

The best approach in dynamics to make a list of all the forces, their magnitudes, directions and their points of applications. The next step is to study the effects of these forces on the object on which they act. By equilibrium i mean that by 2nd law Fnet=0.
